Normal sudoku rules apply. Digits in a cage sum to 15 and do not repeat. Digits along the thermometer increase from the bulb.
Solution code: Row 5 followed by column 5 (18 digits, no spaces).

2 or 3 star for me, very clever break in, but once you see the break in and a few more neat logic steps, it proceeds directly. I really enjoyed the logic on this one. Thanks!

13 cages summing to 15 took me around 13+15 minutes to solve. Very nice puzzle!

Very nice and interesting, not too hard when you spot how to do this. Thanks!

Nice killer puzzle that make you think about the nature of a particular type of cage.
3* diff for me.

Thank you for the lovely puzzle. I am so happy when there is a lot of killer in a sudoku. But I would give it a 2* rating according to my solving time.
